'IYPOGRAPHIC MATRIX-CASE EQUIPMENT.

Application led February 19, 1924.` Serial No. 693,855.

To all cli/0m it may conce/Mt.'

Be it known that I, F RANK HINMAN n i HillN roN'ig'a citizen of the United States of r case equipment for type casting and similar typographicmachines and refers to niatrix cases in which the matrices are assembled in a fram-e in rows and columns. A. matrix case of the` kind referred to, as well as a machine in which it is adapted to be employed, i's basically disclosed in United States Letters Patent No. 625,998, dated May SO, i899, In such a matrix case the matrices are ohlong blocks, rectangular in cross section, one end heilig furnished with a` character or formative cavityand the other end with a centering cavity usually conical in shape for engagement with a centering device for clamping and pressing each matrix against the mold when a cast is to be made.

The main object of the presentinvention is to so construct the matrices and the supporting' bars therefor that each .matrix is separately supported or controlled so that its lateral vmovements are limited and the accumulated wear of the matrices of a row or column is prevented from allowing the displacement of a single matrix to such an extent as would interfere with its accurate register or' presentation to the mold of the machine.

In the present invention the matrices are suspended or supported by a series of parallel bars provided with approximately semicircular notches or recesses and the matrices are furnished with annular or circular grooves for the reception of the bars whereby each matrix is supported or confined within a circular cell. Other objects of the invention will hereinafter be particularly pointed out or will otherwise appear in conneetion with the description of the embodi-- ment of the invention illustrated in the accompanying drawings in which Fi'g. l is a plan view of a matrix case embodying the present invention,

Fig. 2 is a side elevation thereof,

F 3 is af vertical section on mately line 3 3 of Fig. 1,

Fig. t is a vertical section on approxif mately line 4--4 of Fig. l,

Fig. 5 is a horizontal section on approximately line 5 5 of Fig. 3, the matrix case being shown in plan,l

Fig. 6 is a plan view of one of the suspension bars, and

'Fig 7 is an elevation of one of the matrices.

f The matrix case comprises a frame l, this frame being generally of usual and well-` known construction and being box-like in form with an opening through it for the accommodation of the matrices. On the top of the frame l is a cover plate 2 providedl with a. series of perforations or openings 3L coinciding, when the matrices are assembled in the matrix case, with the centering` cone holes 4 in the matrices 5 (Fig. 7)

The matrices 5 are oblong blocks, rectangular in cross section and furnished as hitherto with a character or formative cavity 6 in one end and a conical centering cavity 4 in the other end. In accordance'with the present invention each matrix is provided with an annular groove 7 of an approximate width and depth to accommodate the suspension bars, this groove forming the cylindrical stem portion 8 of the matrix, as shown in Fig. 7. The suspension bars 9 are provided on each of their side edges with approximately semi-circular grooves or notches 10, the bars being adapted to enter the matrix grooves 7 of two rows of matrices whereby the matrices are supported by the bars, and the notches l0 being provided to accommodate the stem portions 8 of the matrices. The bars 9 are arranged in parallel rows between the rows of matrices so that the opposed edges of two neighboring bars substantially meet (Fig. 5) and the grooves l0 of two neighboring bars form circular cells or chambers each accommodating a matrix, the shoulders of y which above and below the annular groove 7 Contact with the approxibars and cause the bars to support the matrix. The ends of the bars 9 are supported in the end bars 11, 12, which are provided with grooves for the reception of the bars 9. Then the matrices 5 and the bars 9 have been assembled, the parts 5, 9, 11, 12 are then placed. lbodily wit-hin the :trame 1. The frame 1 is provided with suitable grooves 13, 11i, for the reception of the end bars 11, 12, respectively, for the support of the latter. These parts are secured in position within the die case frame by the cover plate 2, the ends of which slide under catches 15, 16, on the ends of the die case frame. The plate 2 is prevented from mor-ving laterally of the die oase by slight ridges 17. In order to remove the plate, one edge has to be lifted above one of the ridges 17.

I claim:

1. A matrix case comprising a frame, matrices therein arranged in a ro-w, each matrix being provided with an annular groove providing a matrix stem portion, and a bar detachably supported in thel frame and entering thev matrix grooves of the row of matrices to support said row, said bar being provided with lateral, approximately semi-circular notches to accommodate said matrix stem portions.

2. A matrix case comprising a frame,1nat riCes therein arranged in rows, each matrix being provided with an annular groove providing a matrix stem portion, and a series of parallel bars detachably supported in the frame, each bar entering the, matrix grooves ot two rows of matrices, whereby the matrices are supported by the bars, and each bar being provided with lateral, approximately semi-circular notches along each side thereof to accommodate the stem portions of said two rows of matrices.

3. A matrix case comprising a frame, including two removable end bars, matrices in the trame arranged in rows, each matrix being formed with an annular groove providing a matrix stem portion, and a series ot parallel bars detachably supported in said end bars ot the frame, each bar entering the matrix grooves of two rows of matrices,

whereby the matrices are supported by the bars, and each bar being provided with lateral, approximately semi-circular notches along each side thereof' to accommodate the stem portions of said two rows of matrices.
